About NAAA

The NAAA Certificate of Appraisal is the appraisal of choice for the IRS, U.S. Customs, courts, and financial institutions around the globe. Since 1980, NAAA has set the standard for aircraft appraisal.

NAAA Firsts

  • First with a computer program and extensive Database that is reviewed and/or renewed every month. Not a static source like a the printed guides.
  • First to have trained appraisers who physically examine the aircraft, log books, all equipment and systems.
  • The first and only organization to establish rules of professional conduct for aircraft appraisers.
  • First with helicopters and home built aircraft in our database.

NAAA Computer Program

Data for the program is upgraded monthly by researching lending institutions as to actual sales prices, (the NAAA is the only organization of its kind that is privy to this information) and the appraisals of the NAAA associates. Avionics and other systems are researched as to value, in all there are over 140,000 pieces of data reviewed and/or renewed every month. The program is then delivered to all appraisers to be used at the beginning of the following month, so there is never a question of the accuracy of a NAAA appraisal.

How it works . . .

As the information is entered into the program, the aircraft is electronically disassembled and then reassembled using information collected by the appraiser during his physical inspection. The program then generates the "Green Airframe Value" Then adds back in the avionics and all other system’s depreciated values to arrive at the "Fair Market Value".

During the physical inspection the appraiser grades the airframe, paint, interior, and deicing equipment using exacting NAAA guidelines. The grading is on a 1-10 basis; each number grade directly affects the appraised value of the aircraft when entered into the computer program.


  • Airframe total time
  • Engine status (TBO, New, OH, Reman etc.) and residual value.
  • Propeller status and residual value.
  • Airframe and engine modifications
  • Avionics are cataloged and valued.
  • De-ice equipment condition and value.
  • All systems, and instrumentation is inventoried and valued.
  • The appraiser then generates the report in which any items that may be deemed important to the client is mentioned in detail.

Remember if NAAA isn't on the report . . . it is not an appraisal!
